项目摘要

DESCRIPTION (provided by applicant): Increasing evidence suggests that disturbances in attention and working memory may contribute to the development of specific language impairment (SLI) and stuttering. However, how a detriment in these functions interacts with both linguistic and motor aspects of communication development in creating the unique clinical profile of each disorder remains uninvestigated. One productive and innovative approach to understanding the role of attention and working memory in developmental communication disorders may be a comparative study of these functions in typically developing children, children with SLI, and children who stutter. A strong collaboration between the faculty of Speech, Language, and Hearing Sciences (SLHS) and Psychological Sciences (PSYC) at Purdue provides a tremendous pool of expertise in both typical and disordered speech and language development and thus presents an excellent opportunity for such a comparative approach. Further, the issues of attention and working memory in SLI and stuttering are highly relevant to the research programs of multiple SLHS and PSYC faculty, yet not a single laboratory in these departments presently focuses on these questions. Research into the role of attention and working memory in developmental speech-language disorders may be especially amenable to the electrophysiological approach because of its well-established methods for investigating these cognitive processes and its ease of use with children. Therefore, the goal of this application is to hire Dr. Natalya Kaganovich as a tenure-track assistant professor with a joint appointment in SLHS and PSYC and with a research focus on the behavioral and electrophysiological indices of attention and working memory in developmental communication disorders. Dr. Kaganovich is a post-doctoral researcher in SLHS and PSYC and has already begun to investigate questions related to attention and working memory in both typically developing and speech disordered children and adults. While drawing on the expertise of the current faculty, she would be able to create a research program that not only forges new connections between existing areas of SLHS and PSYC, but also contributes to research of significant public health relevance. PUBLIC HEALTH RELEVANCE: The proposed faculty hire will foster interdisciplinary collaboration between the faculty of SLHS and PSYC aimed at understanding the role of attention and working memory in developmental communication disorders, such as SLI and stuttering. Resultant research findings will help create Intervention techniques that are better suited to the cognitive needs of children with these disorders.

描述（由申请人提供）：越来越多的证据表明，注意力和工作记忆障碍可能导致特定语言障碍（SLI）和口吃的发展。然而，这些功能的损害如何与语言和运动方面的沟通发展相互作用，创造了独特的临床特征的每种疾病仍然没有调查。一个富有成效的和创新的方法来理解注意力和工作记忆在发展性沟通障碍中的作用，可能是一个比较研究这些功能在典型的发展中国家的儿童，儿童SLI，儿童口吃。普渡大学的言语，语言和听力科学（SLHS）和心理科学（PSYC）学院之间的密切合作为典型和无序的言语和语言发展提供了大量的专业知识，从而为这种比较方法提供了绝佳的机会。此外，SLI和口吃中的注意力和工作记忆问题与多个SLHS和PSYC教师的研究计划高度相关，但这些部门目前没有一个实验室专注于这些问题。对注意力和工作记忆在发展性言语语言障碍中的作用的研究可能特别适合于电生理学方法，因为它已经建立了研究这些认知过程的方法，并且易于在儿童中使用。因此，本申请的目标是聘请Natalya Kaganovich博士作为终身助理教授，在SLHS和PSYC联合任命，并重点研究发展性沟通障碍中注意力和工作记忆的行为和电生理指标。Kaganovich博士是SLHS和PSYC的博士后研究员，他已经开始研究与注意力和工作记忆有关的问题，包括典型的发育和言语障碍的儿童和成人。在利用现有教师的专业知识的同时，她将能够创建一个研究计划，不仅可以在SLHS和PSYC的现有领域之间建立新的联系，而且还有助于重大公共卫生相关性的研究。公共卫生关系：拟议的教师招聘将促进SLHS和PSYC教师之间的跨学科合作，旨在了解注意力和工作记忆在发展性沟通障碍（如SLI和口吃）中的作用。由此产生的研究结果将有助于创造更适合这些疾病儿童认知需求的干预技术。
